WRENCH FOR ,ME AT-CHOPPERS.

SPECIFICATION forming part of Letters Patent No. 760,532, dated May 24,1904.

Application filed March 25, 1904.

To aZZ whmn it may concern:

Be it known that I, AL IN J. GERHARDT, a citizen of the United States,residing at Milwaukee, county'of Milwaukee, and State of Wisconsin, haveinvented new and useful Improvements in Wrenches for Meat-Choppers, ofwhich the following is a specification.

My invention relates to improvements in wrenches for meat-choppers.

The object of my invention is to provide a form of wrench adapted to beused for adjusting the annular holding-nut of meat-choppers similar tothose shown in the patent to Baker, No. 339, 834:, dated April 13, 1886.In the meat-choppers of that class the meat is forced through aperforated plate which is held in position by a nut engaging themarginal edges of the plate and provided with both lateral and radialknobs, some of which are frequently broken in use.

My invention contemplates a form of wrench which can be used on machinesof various sizes and which is adapted to engage either the lateral knobsor the radial knobs, as desired.

In the following description reference is had to the accompanyingdrawings, in Which Figure 1 is a rear view of a meat-chopper with myinvention applied thereto in position of use and as it appears whenengaging one of the lateral knobs of the holding-nut. Fig. 2 is a sideview, partly in section, showing my invention as it is used for engagingone of the radial knobs on the holding-nut. Fig. 3 is a detail view ofthe adjustable fork for engaging the radial knobs.

Like parts are identified by the same reference characters throughoutthe several views.

In the meat-choppers of the above-mentioned type the shaft 1 is incasedin a bearing-thimble 2. The wrench comprises a bar 0, having an aperture4 near one end adapted to receive the bearing-thimble 2 and a slot 5extending from said aperture 4 toward the end of the bar, the slot 5being adapted to receive one of the lateral knobs 6 on the Serial No.199,927. (No model.)

holding-nut 7. By adjusting the wrench, as shown in Fig. 1, with thebearing-thimble 2 entered in the aperture L and with the knob 6projecting into the slot 5 it is obvious that the nut can be readilyturned to remove or replace it in position of use. Where the knobs 6 arebroken, as indicated in Fig. 2, a fork 8 is used to engage the radialknobs 9 on the ring 7 The fork 8 is provided with a shank 10, whichpasses through the slot 5 in the bar and is provided with aclamping-nut11, which 1 when-turned up tightly against the bar will bind the forkforcibly in position. By loosening the nut 11 the fork 8 may be adjustedto any desired position, and thereby adapted to machines of varioussizes. I/Vhen in use, one of the radial knobs 9 is entered between thearms of the fork, as indicated in Fig. 2.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A wrench for adjusting the holding-rings of meat-choppers, comprisingthe bar having an aperture near one end adapted to receive thebearing-thimble of the meat-chopper shaft, said bar being also providedwith a slot adapted to receive lateral projecting knobs on theholding-ring of the meat-chopper.

2. A wrench for adjusting the holding-rings of meat-choppers, comprisinga bar having an aperture near one end adapted to receive thebearing-thimble of the meat-chopper shaft, said bar being also providedwith a slot adapted to receive lateral projecting knobs on theholding-ring of the meat-chopper, together with a fork, adjustablymounted on said. bar and adapted to engage radial knobs on themeat-chopper holding-ring.

In testimony whereof I affix my signature in the presence of twowitnesses.

ALI/VIN J. GERHARDT.
